of cane; but it will be readily understoodA that the cultivator is in many respects well adapted for other purposes, and I do not desire to be understood as Vlimiting the invention to cane-cultivators only.

The object of the invention is to provide a simple and efficient Vcultivator provided with means for thoroughly scraping 0E the excess dirt, covering the seed-cane or uncovering the row, for cleaning the row, taking the dirt o from the plant-cane, for shaving the stubblecane, and for cleaning the stubble-row.

A further object of the invention is to provide a cultivator of the class described with a revolving scraper and small plows readily' adjustable from or toward'each other and reversible for the purpose of coveringv or uncovering the row.

A further object is to provide the cultivator with horizontally-disposedY revolving Shavers.

Other objects of the invention are to simplify the construction and render the various parts readily adjustable for the desired purposes.

invention is embodied in the novel parts, arrangement and combinations of parts, hereinafter described, and particularly set forth in the claims.

In the accompanying drawings is illustrated a construction embodying the invention; but it is to be understood that the invention is not limited in its useful applications to this particular construction. l

In the drawings, Figure l is an elevation of a cultivator embodying the invention, the same being partly broken away for the purpose of better illustrating the invention.

Fig. 2 is a plan view of the cultivator illustrated in Fig. l.

Referring to the drawings, A indicates a frame provided with axle-shaft B, upon which are'journaled wheels C C, the frame extending forward and constituting the draft devices for the cultivator, or, if preferred, draft means may be connected to the frame in any usual or desired manner. The frame may also be of any desired or suitable construe- ,It will be observed that the upper ends of the chains are connected to arms or the like f, connected to a cross shaft F, which is mounted in suitable bearings on the frame A. The shaft has rigidly secured thereto at a y suitable point-for instance, at one end thereof-a lever F, by means of which the shaft is rocked in its bearings for the purpose of raising or loweringpthe chains and with them the cultivating-frame. Suitable means are 'provided for holding'the shaft in any desired `adjustment, and Vfor this purpose lI provide the lever with 'a suitable pawl F2,`adapted to engage with the teeth of a stationary segmental rack F3. The pawl is provided with any suitable operatingmeans-for instance,

as'indicated at F4. With such and other objects in View the The cultivating-frame E is shown as composed of a central longitudinal beam E and two side beams E2. The side beams are adj ustable toward and from the longitudinal beam by suitable instrumentalities. For instance, I have shown the front and rear transverse bars E3 rigidly secured to the central beam and extending to each side thereof and provided with perforations e. These transverse bars extend through openings e in the side beams E2, and keys or pins are passed through perforatious in the side beams and the perforations in the cross-bars. The forward end of the central longitudinal beam is IOO provided with forwardly-extending connecting-rods G, adapted to be secured at their forward ends to the frame or draft-rigging of the cultivator.l Their connection with the latter is not shown. The cultivating-frame is conveniently provided at its rear with suitable handles for the operator, the same being indicated at H.

At the forward end of the cultivating-frame and suspended therefrom is a revolving scraper J, provided with radial blades j. This scraper is rotatively journaled in suitable brackets depending from the side beams E2, and for the purpose of adjusting the scraper up or down I have shown the brackets as composed of pivoted links K and brace-rods K', which are connected to the links at their lower ends or to the journal of the scraper and extend up beside the beams E2. The brace-rods K are slotted and are adj ustably secured at the desired adjustment to the beam by means of bolts or the like, 7c, passing th rough the slots into the beams. The shaft of the scraper should be sufficiently long to` permit the adjustment of the beams more or less away from the central longitudinal beam, and suitable collars or other devices may be employed, if necessary, on the scraper-journal to` retain the scraper in its correct position and prevent side movement thereof. In rear of the scraper are two small plows L, which, as will be observed, are supported by suitable standards L', depending from and secured in any preferred manner to the side beams E2. The connection is such as to permit the plows being detached and shifted or changed from one beam to the other for the purpose of throwing the moldboards inside or outside, so as to cover or uncover the row. The, plows being carried by the adjustable side beams are adjustable toward and from each other with the same.

M indicates a revolving colter, one provided for each plow and supported in correct relative position thereto by means of bearinghangers M', connected adjustably to the side beams E2-for instance, by means of a bolt 1main frame, of a cultivating-frame carried thereby, a revolving scraper J carried by said `cultivating-frame, plows in the rear of said iscraper, a fluke in the rear of said plows, lshavers depending from said frame back of m, passing through one of a series of holes m' in the bearing-hanger and into the side beam E2.

Immediately behind and extending forward somewhat between the plows is a substantially triangular-shaped iiuke N. This fluke is provided with a vertical standard N', which for the purpose of adj ustnient is screw-threaded and passes through an opening in the central longitudinal beam E'. Suitable jamnuts nare screwed onto the standard, one on each side of the beam, for securely holding the linke in adjusted position, as will be readily appreciated.

In front of the fluke N is a knife-shaped device N2, depending from the central beam. Behind the fluke N are two horizontal rotary shavers O, which are rotatively mounted at i lmain frame, of a cultivating-frame supportl ed adj ustably from the main frame and havthe lower ends of vertical standards O', adjustably connected in any preferred manner to the side beams E2. The standards O' may be connected to the side beams similarly to the iluke N by means of nuts screwed onto the standards O' and engaging the side beams. For the purpose of further strengthening and bracing the shaver-standards I have shown the same provided with suitable collars P, to which at each side are pivoted brace-rods P'. The latter extend up beside and are adjustably secured to the beams E2 by means of bolts passing through one of a series of perforations p in the brace-rods and into the side beams.

In rear of the Shavers O and centrally between the same is a second cleaning-fluke Q, which, like the fluke N, is supported from the central beam E. The connection is convenientlysimilar to that of the fluke N, and the fluke is by means of this connection adjustable vertically.

It will be observed that the forward fluke N has its forward diverging sides vertical and curved or concaved, whereas the rear fluke is triangular in shape and has its forward converging sides beveled downwardly from front to rear.

It is believed that from the above description the operation of the cultivator will be readily apparent to those skilled in the use of such machines.

The machine and cultivator is intended to do all and any work in cane, corn, cotton, or other plants requiringa complete culture. It will either cover or bare off, throw dirt to the plant, or remove it-in fact, is afull and complete cultivator and labor-saving machine.

Having thus described the invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a cultivator, the combination with a main frame, of a cultivating-frame carried thereby, a revolving scraper J carried by said cultivating-frame, plows in the rear of said scraper, a fluke in the rear of said plows, and shavers depending from said frame back of said linke, substantially as described.

2. In a cultivator, the combination with a said linke, and a second fluke in rear of said sha'vers and centrally between the same, subi stantially as described.

3. In a cultivator, the combination with a main frame, of a cultivating-frame supported adj ustably from the main frame, arevolving scraper .I carried by said cultivating-frame,

i plows in the rear of said scraper, a fluke in the rear of said plows, shavers t depending from said frame back of said fluke, and a second fluke in rear of said Shavers and centrally l between the same, substantially as described.

4:. In a cultivator, the combination with a IOO IIO

In testimony whereof I afx my signature in presence of two Wltnesses.
